Hi all,

Is there a way in Emacs to detect a window switch? Basically, I'd like
to perform an action when a window showing a particular buffer gains or
loses focus. Is there a hook or something that exposes this to Elisp?

TIA

Joost

Did you try the "global" part?  If it doesn't work, please report a bug.

Thanks, martin
